CAR-COUPLING.

SPECIFICATION forming part of Letters Patefit N0. 373.854, dated November 29, 1887, Application filed September 3, 1887. Serial No. 248,726 (No model.)

To all whom/it may concern.-

Be it known that we, SAM SPARROW RUN- DELL and LAFAYETT J ONES DOGGETT, citizens of the United States, residing at Delhi, in the parish of Richland and State of Louisiana, have invented new and useful Improvements in Car-Couplings, of which the following is a specification.

Our invention relates to improvements in carcouplings; and it consists in certain novel features, hereinafter first fully described, and then pointed out in the claims.

' In the accompanying drawings, Figure 1 is a perspective view of our improved coupling. Fig. 2 is a longitudinal section. Fig. 3 is a transverse section, and Fig. 4 is a crosssection through the head-of the pin-guide.

Referring to the drawings by letter, A des- -iguates the draw-head, adapted to be secured ,to the car in any desired manner.

Within the draw-head we provide the longitudinallysliding block B, of the usual construction; In the forward end of the draw-head we provide the coupling-pin G and the guide D therefor. The coupling-pin is provided near its upper end with the longitudinally-slotted enlargement E, through which a pin, F, on the upper end of the pin-guideprojects. The pinguide D slides vertically in an opening or slot, E, in the forward end of the draw-head, and its lower end is provided with an enlargement or head, G, having a concave outer face and vertical flanges or offsets Hon its side edges. The vertical slot in the draw-head corresponds in cross-section to the outline of the enlarged head G, so as to-causeit to movein a true vertical direction, and the couplingpin fits in the concave face of the enlarged head. A coiled spring, I, is arranged around the pin-guide and bears between the top of the draw-head and the enlarged head of the pin-guide, so as to press the pin-guide and the pin normally downward. The upper extremity of the pin is provided with an eye, J, to which we se-- cure one end'of a rope or chain extending to the side or top of the car.

The operation of the device will be readily understood. When the cars are uncoupled,

the coupling-pin and the pin-guide are held upraised by the longitudinally-movable block B in the draw-head. In coupling, the link enters the draw-head and shoves the block B back from under the pin, which then falls into engagement with the link by the force of gravity. The coiled spring H simultaneously acts on the pin-guide, forcing it downward and thereby causing the pin F to strike against the lower end of the slot E and force the pin positively into engagement with the link. The operation of uncoupling of course is the reverse of that just described.

It will be observed that our device is very simple in construction and efficient in operation, and that by its use the necessity of the brakeman going between the cars is entirely obviated.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is- I 1. The combination, with the draw-head, of the longitudinally-sliding block, the pin, and the vertically-movable pin-guide in rear of the pin, substantially as specified.

2. The combination of the draw'head, the sliding block, the pin having a slotted enlargement in its upper portion, and the pin-guide S AM SPARROW RUN DELL. LAFA YETT JONES DOGGETT.
